IMPROVEMENT IN PAPER-FASTENERS.

Specification forming part of Letters Patent No. 125,682, dated April16, 1872 5 antedated April 2, 1872.

SPECIFICATION.

To all whom it may concern: y

Be it known that I, J oHN (l. JENSEN, of Chicago, in the county of Cookand State of Illinois, have invented a new, useful, and ImprovedMetallic Paper-Fastener; and I do hereby declare the following to be afull, clear, and exact description thereof, which will enable othersskilled in the art to which my invention appertains to make and use thesame, reference being had to the accompanying drawing forming part ofthis specification, in which- Figure l is a top view ofthepaper-fastener as stamped from sheet metal, prior to being folded foruse. Fig. 2 is a side view of the same when folded. Fig. 3 is aperspective view of the same when folded. Fig. 4 is an edge view of thefastener, inserted in a hollow metallic blade employed in connectionwith the fastener for passing the same through paper; and Fig. 5 is aside View of the blade.

Similar letters of reference indicate like parts in the several figuresof the drawing.

My invention relates to a metallic fastener for fastening together twoor more sheets of paper, in connection with a hollow metallic blade formaking the necessary perforations in the'paper, with which and at thesame time to insert the fastener, and so that one or more ofthe sheetsof paper may be removed, either from the front or back, Without removingthe fastener; andthe improvement consists in the construction of thefastener and of the blade i in connection therewith, for the purposesaforesaid, which will be more fully understood from the followingdescription:

In the drawing, A represents the metallic fastener in the form asstamped from thin O is a hollow metallic blade, of any suitable metal,made tapering, pointed, and sharp upon both of its edges.

In using my metallic fastener, I insert either of the ends a and b inthe opening at the heel of the blade, as shown at D, and then bend theother ends of said parts a and b downward and laterally, as shown at dd, forming a head or base by which the blade is pressed and forcedthrough the paper, and in connection therewith one-half of the fastener.The blade is then removed from the fastener and the ends ofthe fastenerpressed and flattened down upon the sides of the paper, thus forming afirm ,-secure and double fastener to the several sheets of paper. Itwill be observed that when it is desired to remove any of the .sheets ofpaper, fastened as aforesaid, from the front or back, it is onlynecessary to bend the points or parts of the fastener on the sidedesired back to their original position on a line With the openingthrough the paper, without removing the fastener wholly from the paper.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is

l. The double metallic paper-fastener B, formed of one piece of metal,slit or opened from its ends to near its center, and provided with theprojections C, and folded together, in the manner substantially as andfor the purpose'deseribed.

2. The combination of the blade C with the fastener B, substantially asandrfor the pur pose described.

The foregoing specification of my invention signed by me this 22d day ofJune, A. D. 1871.
